Permatex Epoxy: Precision-Engineered Bonding for Every Application

When it comes to chemical adhesives built for demanding environments, few names carry the credibility of Permatex. Their lineup of epoxy adhesives is among the most thoughtfully developed in the industry — each formula engineered not just to bond, but to solve specific real-world repair challenges that generic epoxies simply aren't designed to handle.

A Full Lineup Built Around Specific Needs

What sets Permatex apart in the epoxy category is their commitment to substrate-specific and application-specific formulations. Rather than offering a one-size-fits-all product, Permatex has developed a comprehensive core line to match the right adhesive to the right job.

• Steel Weld® Epoxy — Permatex Steel Weld is a steel-reinforced, multi-metal formula that eliminates the need for welding or brazing. It bonds aluminum, brass, chrome, copper, iron, and stainless steel, and once fully cured, it can be drilled, threaded, and machined. It delivers a shear strength of up to 4,500 PSI and is resistant to water and solvents.
• 500° High Heat Epoxy — Designed specifically for under-hood automotive environments, this is the first and only high-temperature liquid syringe epoxy in its category. It withstands twice the temperature range of standard epoxies, making it ideal for applications where heat can reach 400°F or more.
• 1-Minute & 5-Minute Gel Epoxies — These fast-setting formulas feature a no-drip gel consistency for mess-free application. A built-in Blue Dye Indicator disappears when the epoxy is properly mixed and ready to apply, eliminating guesswork and wasted material. The 5-Minute Gel delivers a holding strength of up to 3,400 PSI.
• 2 Ton Epoxy — A general-purpose, clear high-strength epoxy that remains repositionable for up to 15 minutes and bonds ceramics, fiberglass, metal, concrete, and more.
• Marine H2 Hold Epoxy — Formulated to stick and cure underwater, this marine-grade epoxy reaches an industrial strength of up to 4,000 PSI and is effective in both salt and fresh water — ideal for fuel tanks, drains, and boat hulls.
• Cold Weld 2-Part Epoxy — A 15-minute, two-part adhesive and filler system designed to replace welding and brazing in metal repair applications.

Innovation That Addresses Real User Problems

Permatex's epoxy development is grounded in hands-on research with end users. The Blue Dye Indicator technology in their gel formulas is a direct result of recognizing that improper mixing was a common source of failed bonds — the visual cue confirms when the epoxy has transitioned from a blue tint to clear, signaling it is fully combined and ready for application. The no-drip gel formula prevents runoff on vertical or overhead surfaces, a practical improvement over traditional liquid epoxies.

Across the lineup, Permatex epoxies are designed to require no clamping, resist common shop fluids, and deliver permanent, structural-grade bonds on metals, plastics, ceramics, rubber, fiberglass, and more. Whether you're tackling an under-hood repair, fixing marine hardware, or bonding rigid materials around the garage, the Permatex epoxy range has a purpose-built solution ready for the task.
